The present invention relating, an iml-.

cated, to valves, has for its object the im. a valve of the self-closing end the mvinion of moana for preventivi the deposition of sediment or other materia on the valve aeat that might keep the vulve from forming a perfect closure.

To the accomp and -related endo said invention, then, coneiste of the means hereinafter fully deiiribod, and vparticularly pointed ont n the calms.

'llie annexed drawi and the following description set forth in etail certain mechaiiiiin embodying the invention, such disclosed means constitutin however, butl one of vvaiioiui mechanical orme in which thi'.I principle of the invention may' be need.

In aaid annexed drawing-Figure 1 in n iiide elevation of a faucet 'wherein hes been incorporated my improved conrnction of valve; Fig. 2 is a longitudinal vertical tion of such faucet and valve; andl Fig. 8 is acroes'eection on the line 3-8 of the precedi Re ri'ing to the illustrative coiistrnction of the drawin 'ust described, the faucet there shown wi eeen to comprise a p pe o r zeilig 1 hav' an u wardly projecting hren erboso! tis ormedwithata r seat or'the reception of the turning p ug or. dem .6. The latter is provided intermediate between 'ita enda with a packing .rt 6 that 'conforma to the taper of suc A handle Bia mounted on the outer end of the plug, while at its inner endl auch haa an eceeiitric rejection or cum 4 re of the casin 1. The aing 1 is provided with an nnnu ar nat of conical form that faces in a direction awa from the end 4 of the plug tlint thus roJecte within the casing nn: has im opening 11 at its center throu which the liquid or other fluid is desi e to pasa when per mitted by the vulve? The latter consists of a cylindrical cupthe closed end of which is provided with openingu B and ig made conical in form and properly inclined to ishment of the foregoing l Mm..-

. have substantially n line contact with the edge of' annular seat 9. Such closed end of the valve which thus forms the valve head has a rod 10 which extend" longitudien nnlly through opening 11 in the valve neat into position to contact with cam 4 on the inner end oil the turning plug 5.

From the foregoing conatriict'on it will be seen that the valve ia mov .ble lengthwise in the e8' pipe to and from the seat. When the valve is moved from its neat, the li uid is deeignod to flow through theholea 8 t erwin, en thence throu li .the opening 11 inl the valve aeat,`the latter ing large enou to atlord passager@ around the valve stem 0. When the valve is closed it obviously contacts with the seat onacincnlerlinoneareribaxiethanthe h'olea 8 eo that the latter are ,in elaet'cloaed. The valve is normally retained nanelieloesd tion by the garenne of behind it, but it may desired by turning the pl 5 which een. the m 4 toengagewith eatemlao'aato' :Hagemann fisnuuiinita xgalnt. liti:- z
